EFISIENSI BATERAI LITHIUM-ION DENGAN MENGGUNAKAN METODE COULOMB COUNTING

Abstract

The result of regenerative braking requires storage in the form of a battery so that it can be used again at a certain time. Batteries are one of the commonly used electrical energy storage media and have various provisions according to needs. To avoid overcharging and overdischarging the battery, a battery monitoring system is needed so that it can charge and discharge safely. In this study a battery monitoring measuring instrument was designed that can measure the estimated value of the State of Charge (SOC) of the battery. To obtain an initial estimate of the battery's SOC, then use the Coulomb Counting (CC) method to estimate the SOC when charging the battery. From the results of this study, when the value of the engine speed for the input voltage is greater, the charging time, the charge entering the battery, and the estimated change in SOC(t) are greater. Electric motorcycles are currently developing in the automotive industry. Because it is environmentally friendly and can save energy and long-term costs. Some of the problems in electric motorbikes are battery failure which will result in failure of the entire vehicle system. To avoid this, the battery must be used wisely, including estimating the state of charge (SOC) of electric motorbike performance so that the maximum rated usage is known and then determining where the battery must be recharged.
